民用飞机在寒冷地区地面停留较长时间后,由于外部环境温度过低,会导致机舱内温度降低到难以满足人员的热舒适要求,因此在人员登机前需要对客舱进行加热。加热的方法,一是通过飞机自带的环控系统进行,二是采用空调车送风加热,也可以在飞机座舱铺设地板快速加热装置进行辅助加热。本文基于某型民用飞机座舱的真实几何参数,建立了其座舱二维加热模型,对多种加热方案的效果进行了评 Civil aircraft in the cold area after a long stay on the ground, due to the external temperature is too low, it will lead to the cabin temperature is reduced to meet the thermal comfort requirements, so before boarding passengers need to be heated. Heating method, one through the aircraft’s own control system, the second is the use of air-conditioned car air supply heating, can also be installed in the aircraft cockpit fast heating floor heating device for auxiliary heating. Based on the real geometrical parameters of a certain type of civil aircraft cockpit, a two-dimensional heating model of the cockpit is established and the effects of various heating schemes are evaluated
